Abstract (en)

[origin: EP0443289A2] A printed circuit board inspection device includes a lighting system for use with the series of cameras associated with the printed circuit board inspection device which is essentially domed in configuration, and which incorporates a plurality of selectively controllable light emitting diodes for developing desired lighting patterns. The light emitting diodes are arranged within the domed fixture to form an array of defined latitudes and longitudes, and are capable of selective activation to develop the particular lighting patterns which are desired. This permits an acquisition of images useful in developing a "topographical display" of the acquired image, which is useful in enhancing the subsequent inspections which are to be performed. <IMAGE>
